I've enjoyed your books about other platforms. They are very thorough, the Onion platform would benefit very much. I hope you decide to write this one.

RE: Playing with oled-exp
Just updated from b234 to b236, now the Image function of the OLED Expansion Control of the Control Panel displays the image in a torn, skewed manner. It worked correctly in b234. Worked correctly in b234.

RE: Oled Screen
@Boken-Lin, are the red and black connections at the bottom of the diagram correct?
Comparing it to the diagram on the GPIO tool on the Console and the diagram of the Expansion dock, it looks like in this diagram, 2.8V of the Omega (black) is tied to GND of the Oled and GPIO26 of the Omega (red) is tied to 2.5V of the Oled.
The Green, gold and red connections at the top of the diagram make sense, as GPIO20 (I2C_SCL), GPIO21 (I2C_SDA) and 3.3V.
